Hi, I recently was unable to load Zero-Hour from disc after a big Windows 7 update and had the following message appear on screen...
"Please login with administrator privileges and try again"
Even login in as admin, it doesn't load.

I have found the windows 7 update responsible for this.
It's called: 'Security update for windows 7 for x64-based systems KB3086255'

I have enjoyed playing this game for many years and was gutted when I couldn't.
Unfortunately I had not updated windows in some time and had around 30 updates. It took a while to find the problematic one to uninstall😒

Well if anyone has had the same problem on Windows 7, uninstall this update and should be working again 👍
